Abstract: 792,665. Endless conveyers. COAL INDUSTRY (PATENTS), Ltd. May 2, 1955 [May 5, 1954; Nov. 4, 1954], Nos. 13092/54 and 31963/54. Class 78 (1). In a conveyer system consisting of a plurality of complementary sections each comprising an endless conveying element, the endless conveying elements of two or more of the sections being driven from a single source of power, each section is provided with a power-receiving device and a power-transmitting device, one of which devices is accommodated in a jib which serves for the connection of the section to another section and is pivotally connected to the section for rotation about an axis perpendicular to the plane containing the major longitudinal and transverse axis of the section. The leading section may be connected to and receive its drive from the delivery end of a main conveyer, an intermediate portion of a main conveyer, or a stationary drive unit. In one form, Fig. 6, each section comprises a frame 26 and a conveyer belt 20 which travels around rollers 23, 23A journalled in the frame. Roller 23A is connected by bevel gearing to a drive-receiving socket 25, rotatable about the axis of drum 23A and connectible with a drive-transmitting spigot on a succeeding section, a main conveyer, or a stationary drive unit. Roller 23 is geared to a snub roller 19 which in turn is connected by bevel gearing 18 to a shaft 17 about which swings a jib 16 containing a sprocket chain 16A connecting shaft 17 to the shaft 21 of drive-transmitting spigot connectible with the socket 25 of a preceding section. Shaft 21 preferably includes an overload release-device. In another form, Fig. 9, an enclosed shaft 31 transmits a drive directly from a drive-receiving socket 30 to a bevel gear 35 at the other end of the section. Bevel gear 35 meshes with a pair of bevel gears 35A, one on a shaft 34 and the other on a shaft 32 carried by a jib 33 swingable about the shaft 34. A spigot 29 on the end of shaft 32 transmits the drive to the preceding section, the jib 33 also being secured to the shaft housing of the preceding section. Bevel gearing and a transverse inclined shaft 37 connects shaft 31 to drum 38 at the leading end of conveyer belt 36. In the Fig. 12 form, shaft 31 is replaced by a chain drive 39, and shaft 32 by a chain drive enclosed in a jib 41, the two chain drives being connected by shaft 40 about which jib 41 is swingable. In the forms of Figs. 9 and 12 height adjustment is effected by swinging the supporting arms of the ground wheels about a horizontal pivot on the frame. In a further form, Fig. 18, similar to that of Fig. 9, the supporting arms 57 of the ground wheels are swung about shaft 56 by a cable 58 passed around a drum 55 on shaft 56, to which it is secured, and also over pulleys 59 to an arm 60 on a threaded sleeve 62 which is traversed along a threaded shaft 63 by rotating a hand wheel 64. Drive may also be transmitted between the sections by compressed-air piping having flexible joints at the axis of turning of the jib so that fluid may be passed along the sections by a pipeline to feed separate fluid motors on the various sections.
